Liltotto Lamperd is a Quincy and a member of the Wandenreich's Stern Ritter with the designation "G the Glutton".

Her power is called "The Glutton." Liltotto can consume whatever she chooses by shifting her mouth outward into a extended form, allowing it to become a gaping maw of jagged teeth which eats whatever she pleases. However, as a side-effect, this ability leaves Liltotto in a constant state of hunger.

She is shown to be the more rational and intelligent character from amongst the female Sternritter.
